Identification of the priority regions in the customer water meters replacement using the AHP and ELECTRE methods

The aim of this study is to determine the priority areas in the meter replacement or rehabilitation by using an integrated methodology combining the AHP and ELECTRE I methods to reduce the non-revenue water. For this, a total of 7 criteria such as the Water Consumption Rate, Mean Meter Age, Faulty Water Meter Ratio, Region Population Rate, Customer Loyalty Percentage, Average Operating Pressure and Calibrated Age were considered. The AHP method was applied to calculate the weights of the criteria and then a model based on weights of criteria was developed using the ELECTRE I method. The model based on AHP and ELECTRE I methods was applied by taking into account the field data records for 7 criteria and the priority regions in water meter replacement were determined. This study will make significant contributions in the scope of minimizing the losses caused by the meters, reducing the costs in meter management and making the most benefit in meter replacement.
